7447709470 Description

Short technical summary and product information.

The 7447709470 is a shielded surface-mount power inductor from Würth Elektronik's WE-PD series. It has an inductance of 47 µH ±20% measured at 1 kHz / 250 mV. The component is rated for a continuous current of 3.8 A (ΔT = 40 K) and features a performance-rated current of 4.9 A per IEC 62024-2-2020. Saturation current is 4.5 A at 10% inductance drop and 5.5 A at 30% drop. DC resistance is 46 mΩ typical, 60 mΩ maximum at 20 °C. Self-resonant frequency is 6.5 MHz typical. Maximum operating voltage is 120 V. The inductor is fully shielded, uses a ferrite drum core with wirewound construction, and is housed in a 1210 (12.00 mm x 12.00 mm) nonstandard SMD package with a maximum height of 10.00 mm. It is qualified to AEC-Q200 Grade 1 for automotive applications and operates over -40 °C to +125 °C. RoHS, REACH, and halogen-free compliant.
